CHECKING FEATURES

ADDITIONAL FEATURES AND REMARKS
Typical application areas include aircraft and missile design

control systems, structural analysis, information processing,
navigation, critical path scheduling, hydraulic and gas
network analysis, satellite computer operation,
communication switching systems, and telemetry data
reduction.
Five distinct input/output systems are standard equipment on
900 Series computers. Information can be processed by bits,
characters, or words, for flexibility and speed. A built-in
priority interrupt system allows efficient handling of a
virtually unlimited number of peripheral input/output
devices. An external Memory Interlace system automatically
provides direct input/output connection to the core memory,
without program intervention, at rates up to 200,000
chars/sec. With SDS 900 Series computers, over 16,000
signals are available for device operation and testing under
program control. Three input/output operations can be
carried on simultaneously. An integrated group of optional
input/output devices - including both low and high density
IBM compatible magnetic tape units - are available from SDS.
System uses silicon solid-state components to widen
operating temperature range and thereby increase reliability
by an order of magnitude. All memory operations and
input/output are parity checked. Low noise coupling for
peripheral equipment insulates the computer system against
outside electrical disturbances which cause errors. The
memory is protected against information loss in the event of
power failure.
Closed loop synchronization of all input/output opertions
assures no inadvertent loss of information.

ADDITIONAL FEATURES AND REMARKS
The SDS 910 and SDS 920 have identical input/output
systems so that a common set of peripheral equipment can be
connected to either machine. The word and number format
and memory of both machines are also identical. The command
list for the 920 is more powerful, making it about 10 times
more capable for internal computing speeds than the SDS 910.
Five distinct input/output systems are standard equipment on
900 Series computers. Information can be processed by bits,

Individual training is made available by the manufacturer to
the user. Control panel wiring is quite simple for a user
with IBM wiring experience.
Operator training is given on the user's own premises.
RELIABILITY, OPERATING EXPERIENCE
Operation with 97% up-time has been achieved.
ADDITIONAL FEATURES AND REMARKS
A mobile electronic memory attachment is available which
sorts, stores, summarizes and selcts data at random as a
100% by-product of normal EAM operations. The system
can be readily transferred from one I/0 device to another.
SEMA operates between card cycles of the IBM (EAM)
machine to which it is attached. The IBM machine
(collators, reproducers, tabulators, etc.) operate at their
normal speed.
As a result of its random access capabilities, the SEMA
2000 can perform important functions, at electronic
speeds, as a 100% by-product of necessary EAM machine
operations; can summarize data "off line" via collators and
other high speed equipment to substantially reduce
accounting machine time; eliminate major sorting, collating
and card handling operations; and eliminate the need for
computations by means of stored tables.
The flexibility of SEMA 2000 enables it to increase the
speed of handling punched cards by as much as 6 1/2
times. It also permits a reduction in costly accounting
machine time, for example, by summarizing details via a
high speed collator and using the accounting machine to
print only the pre-summarized totals in SEMA.
SEMA 2000 can be programmed to provide controls in the
following areas:
Inventory Control Order Confirmation
Sales Analysis Order Allocation
Payroll Production Control
Store Audit Labor Distribution Reports
Pricing Unit Control
SEMA 2000 is an electronic memory unit designed to utilize
conventional EAM tabulating equipment to produce
electronic data processing results at typical EAM prices. It
operates with accounting machines, collators, reproducers,
calculators and punches. With its random access
capabilities, SEMA is able to perform important functions
between card cycles on EAM equipment and thereby
providing increased data processing output.
The transistorized SENA utilizes an electronic memory
drum for random access data storage. It takes its input and
output instructions from EAM equipment, reads selected
data at random and summarizes these data as a by-product
of necessary EAM machine operations.
The SEMA memory drum has a capacity of 2000 tendigit
words and two flags per word. By means of a control
switch, capacity can be increased to 4000 five-digit words
and one flag per word.
Additional memory drums can be added. For instance, with
five drums SEMA can accommodate up to 10,000 ten-digit
words and two flags, or 20,000 five-digit words and one
flag per word.
The following applications demonstrate the ability of SEMA
2000: Order allocation, inventory control and sales
analysis-as a result of a single collator pass. Inventory
control and sales analysis as a by-product of an invoicing
run. Automatic pricing and extending of line items as a by-
product of an invoicing run. Order confirmation, inventory
control and "goods in process" interrogation as a by-product
of a single accounting machine run. Elimination of
calculating machine passes for payroll computationsby
means of stored deduction tables.

PRODUCTION RECORD
Number produced to date 2
Number in current operation 2
Time required for delivery 6 months
COST, PRICE AND RENTAL RATE
Price
Basic System $132,000 and up
PERSONNEL REQUIREMENTS
Training made available by the manufacturer to
users includes programming and maintenance schools.
RELIABILITY, OPERATING EXPERIENCE
All circuits are solid-state and are designed to withstand
wide temperature fluctuations. All connector contacts are gold-
plated. The bulk of the electronic components are Military-
Standard.
Operating Ratio (Good/Attempted to Run Time): 0.995 for
1,000 hour periods, according to manufacturer's records.
ADDITIONAL FEATURES AND REMARKS
The system can be used in either analog and/or digital
hybrid configuration to provide rapid solutions to
transcendental equations.
SPEDAC is a digital differential analyzer (DDA). It employs a
variable number of multiple digital arithmetic units, all of
which operate simultaneously.
SPEDAC 220 computes at 200,000 iterations per second.
Regardless of problem complexity, the entire problem solution
is updated incrementally each 5 microseconds. Various types
of computing elements perform integrations, multiplications,
additions and decisions.
SPEDAC is a combination of the characteristics of general
purpose analog and digital computers. Although all the
circuits are digital, SPEDAC is programmed like an analog
computer, i.e., the original problem formulation is placed in
the machine, with a minimum of programming effort, rather
than a solved, linearized, approximation made by a numerical
analyst.

APPLICATIONS
Scientific applications include simulation, data reduction,
real-time control, optimization, correlation, and dynamic
system analysis.
The field of application encompasses those areas in which
fast and accurate solutions are required for equations of
algebraic, differential, partial differential, simultaneous, non-
linear, and implicit types. These equations may contain
discontinuities, arbitrary functions, trigonometric functions,
exponential functions, logarithmic functions, complex roots,
and factorials.
